Description
本发明涉及通信领域,尤其涉及一种数据传输方法、设备及系统。The present invention relates to the field of communications, and in particular, to a data transmission method, device, and system.
在无线通信网络中,各个设备需要利用频率资源进行信息传输,频率资源也被称为频谱。频谱可以分为授权频谱和非授权频谱。授权频谱是一些运营商专属的频率资源,非授权频谱是无线通信网络中公用的频率资源。随着通信技术的发展,无线通信网络中传输的信息量日益增加,抢占非授权频谱传输信息,可以提高无线通信网络中的数据吞吐量,更好地满足用户的需求。In a wireless communication network, each device needs to use frequency resources for information transmission, and the frequency resources are also called spectrum. The spectrum can be divided into licensed spectrum and unlicensed spectrum. The licensed spectrum is a frequency resource exclusive to some operators, and the unlicensed spectrum is a common frequency resource in a wireless communication network. With the development of communication technology, the amount of information transmitted in the wireless communication network is increasing, and preempting the unlicensed spectrum transmission information can improve the data throughput in the wireless communication network and better meet the needs of users.
现有技术中,数据的传输大多采用HARQ(Hybrid Automatic Repeat Request,混合自动重传请求)的方式。例如,当第一设备向第二设备发送数据后,第二设备会向第一设备反馈ACK/NACK(Acknowledgement/Negative Acknowledgement,确认/否定应答)消息,第一设备根据第二设备的反馈信息确定是否向第二设备再次传输此数据或此数据的其他版本,直到此数据传输正确,这样一次数据传输的过程是一个HARQ进程,每次数据传输的HARQ进程都有一个HARQ进程号码,便于区分不同的HARQ进程。在抢占非授权频谱进行数据传输的场景中,设备成功抢占非授权频谱的信道之后,发送数据的时刻可能是随机的,这导致设备发送数据的时刻可能不是一个完整子帧开始的时刻,即设备发送的第一个子帧可能不是一个完整的子帧,而此时,如何确定这个不完整的子帧的HARQ进程号码成为亟待解决的问题。In the prior art, the data transmission is mostly in the form of HARQ (Hybrid Automatic Repeat Request). For example, after the first device sends data to the second device, the second device feeds back an ACK/NACK (Acknowledgement/Negative Acknowledgement) message to the first device, where the first device determines according to the feedback information of the second device. Whether to transmit this data or other version of this data to the second device until the data transmission is correct, such that the process of data transmission is a HARQ process, and the HARQ process of each data transmission has a HARQ process number, which is convenient for distinguishing different The HARQ process. In the scenario of preempting the unlicensed spectrum for data transmission, after the device successfully preempts the channel of the unlicensed spectrum, the time at which the data is sent may be random. This may cause the device to send data at a time that may not be the beginning of a complete subframe, that is, the device. The first subframe sent may not be a complete subframe. At this time, how to determine the HARQ process number of this incomplete subframe becomes an urgent problem to be solved.
